What is "wqam"

WQAM (560 AM, "Miami Sportsradio 560 WQAM") is a South Florida radio station owned by CBS Radio. The call letters WQAM were jokingly claimed to stand for We Quit At Midnight ... since the station signed off at midnight every night until 6:00 the next morning. Its studios are in Miami Gardens and the transmitter is in Virginia Key, Florida.
